Description

Technical Field

[0001] The invention belongs to the technical field of rice seedling cultivation, and in particular is a deviation correction mechanism of a self-propelled rice seedling cultivation swing plate machine. Background Art

[0002] The self-propelled rice seedling tray machine is an agricultural machine that combines automated seeding technology with a walking function. It is widely used in the rice seedling raising process. It uses mechanized means to automatically supply trays, sow seeds, cover soil, spray water, and output rice seedlings. It also has autonomous movement capabilities and can flexibly adapt to the operational needs of different fields. With the development of agricultural modernization, the level of mechanization in the rice planting process continues to improve. In the rice seedling raising process, self-propelled rice seedling raising tray placing machines are widely used as an efficient and convenient agricultural machinery for placing seedling trays. Although the currently common self-propelled rice seedling raising tray placing machines can realize the basic seedling tray placing function, they are prone to deviation during operation. This deviation problem is mainly manifested in that the walking path of the tray placing machine deviates from the predetermined track due to uneven ground, loose soil or unreasonable structural design of the machine itself during the movement. Once deviation occurs, it will not only affect the neat arrangement of the seedling trays, but may also cause the spacing between adjacent seedling trays to not meet the standard requirements, thereby affecting subsequent sowing and management operations. Therefore, a correction mechanism for a self-propelled rice seedling raising tray placing machine is proposed. Summary of the Invention

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0038] like Figures 1 to 10 As shown, the present invention provides a correction mechanism for a self-propelled rice seedling raising swing plate machine, including a swing plate machine body 1, and also including:

[0039] The guide assembly 2 is placed on the seedling raising ground, and the swing plate mechanical body 1 moves on the guide assembly 2;

[0040] Sliding assembly 4, the sliding assembly 4 is installed on the outside of the wobble plate mechanical body 1 through the limiting assembly 5;

[0041] Stabilizing component 3, which is installed on both sides of the limiting component 5;

[0042] The guide assembly 2 includes two main beams 25, with first docking rods 26 fixedly mounted on the sides of the main beams 25 at equal intervals. A first guide rail 21, a second guide rail 22, a third guide rail 23, and a fourth guide rail 24 are equidistantly arranged between the two main beams 25. Docking blocks 27 are fixedly mounted at both ends of the first guide rail 21, the second guide rail 22, the third guide rail 23, and the fourth guide rail 24.

[0043] The first guide rail 21 , the second guide rail 22 , the third guide rail 23 and the fourth guide rail 24 are sleeved on the outside of the first docking rod 26 through the docking block 27 and installed between the two main beams 25 with the help of nuts. The bottom of the first guide rail 21 remains horizontal with the main beam 25 .

[0044] An annular groove adapted to the first guide rail 21 is provided in the middle of the outer portion of the driving wheel of the wobble plate mechanical body 1, and a rubber pad is provided on the inner wall of the annular groove;

[0045] The swinging machine body 1 moves along the first guide rail 21 and the second guide rail 22 through the driving wheel to swing the seedlings.

[0046] The two main beams 25 are placed at both ends of the seedling field or seedling greenhouse, and the first guide rail 21, the second guide rail 22, the third guide rail 23 and the fourth guide rail 24 are installed between the two main beams 25 through the docking block 27. The swing plate mechanical body 1 is placed on the first guide rail 21 and the second guide rail 22. The seedling plates are placed in the seedling field or greenhouse in turn through the working movement of the swing plate mechanical body 1. The swing plate mechanical body 1 is limited and guided by the first guide rail 21 and the second guide rail 22 to make it move in a straight line, so as to avoid the swing plate mechanical body 1 deviating from the predetermined track during movement due to the uneven ground of the seedling field or greenhouse, causing the seedling plate to deviate.

[0047] It is explained here that the distances among the first guide rail 21 , the second guide rail 22 , the third guide rail 23 and the fourth guide rail 24 can be adjusted according to the width of the swing plate machine body 1 and the width of the rice seedling raising plate.

[0048] like Figure 7-Figure 9 As shown, the limiting assembly 5 includes a movable ring 52 fixedly mounted on the outside of the wobble plate mechanical body 1, and a docking ring 53 is movably sleeved on the outside of the movable ring 52, and a docking plate 51 is fixedly mounted on the outside of the docking ring 53;

[0049] The inner wall of the docking ring 53 is provided with a circular array of circular grooves, and the outer periphery of the movable ring 52 is fixed with a circular array of springs 55. One end of the spring 55 is provided with a limit ball 54, which is correspondingly engaged in the circular groove.

[0050] When the swing plate mechanical body 1 moves to the other end along the first guide rail 21 and the second guide rail 22, the swing plate mechanical body 1 is rotated 180 degrees with the docking ring 53 as the central axis. At this time, the swing plate mechanical body 1 can adjust the direction of the seedling plate swing.

[0051] like Figure 4-Figure 8 As shown, the sliding assembly 4 includes a rectangular frame 41, and two sides of the inner wall of the rectangular frame 41 are provided with sliding grooves 43 for the docking plate 51 to slide;

[0052] The limiting assembly 5 and the swing plate mechanical body 1 are located at one end of the rectangular frame 41, and the driving wheel of the swing plate mechanical body 1 and the first guide rail 21 and the second guide rail 22 are kept vertical;

[0053] The limiting assembly 5 and the swing plate mechanical body 1 slide to the other end of the rectangular frame 41, and the driving wheel of the swing plate mechanical body 1 and the second guide rail 22 and the third guide rail 23 remain vertical;

[0054] The sliding assembly 4 further includes a cylinder 42 fixed to the four corners of the rectangular frame 41. The output end of the cylinder 42 is fixed with a first clamping frame 44. The first clamping frames 44 are connected in pairs by a second docking rod 45. The middle of the second docking rod 45 is fixed with a second clamping block 46 having the same shape as the first clamping frame 44.

[0055] When the driving wheel of the wobble plate mechanical body 1 is located on the first guide rail 21 and the second guide rail 22, two of the first clamping frames 44 and the first guide rail 21 remain vertical, the other two first clamping frames 44 and the third guide rail 23 remain vertical, and the second clamping block 46 and the second guide rail 22 remain vertical;

[0056] When the wobble plate mechanism body 1 and the sliding assembly 4 move to the other end of the first guide rail 21 and the second guide rail 22, the four cylinders 42 push the second clamping block 46, the second docking rod 45, and the first clamping frame 44 downward. Two of the first clamping frames 44 are clamped on the first guide rail 21, and the other two first clamping frames 44 are clamped on the third guide rail 23, thereby supporting the wobble plate mechanism body 1.

[0057] Push the swing plate mechanical body 1 to make the docking plate 51 slide along the slide groove 43 to the other end of the rectangular frame 41 , and the driving wheel of the swing plate mechanical body 1 and the second guide rail 22 and the third guide rail 23 remain vertical.

[0058] The seedling raising plate is placed in the seedling raising field or greenhouse in sequence by the swing plate mechanical body 1 moving along the first guide rail 21 and the second guide rail 22. When the swing plate mechanical body 1 moves to the other end of the first guide rail 21 and the second guide rail 22, the cylinder 42 starts the output end to push the first clamping frame 44 and the second clamping block 46 downward, wherein the two first clamping frames 44 are engaged with the top of the first guide rail 21, the other two first clamping frames 44 are engaged with the top of the third guide rail 23, and the two second clamping blocks 46 are engaged with the top of the second guide rail 22. As the output end of the cylinder 42 continues to push out, the swing plate mechanical body 1 is supported and the driving wheel is disengaged from the contact with the first guide rail 21 and the second guide rail 22, the swing plate mechanical body 1 and the docking plate 51 can be pushed along the slide groove 43 to the other end of the rectangular frame 41. At this time, the driving wheel of the swing plate mechanical body 1 and the second guide rail 22 and the third guide rail 23 remain vertical.

[0059] At this time, the output end of the cylinder 42 contracts in the opposite direction, and the driving wheel of the swing plate mechanical body 1 gradually falls onto the second guide rail 22 and the third guide rail 23, while the first clamping frame 44 and the second clamping block 46 gradually separate from the first guide rail 21, the second guide rail 22 and the third guide rail 23. Since the driving wheel of the swing plate mechanical body 1 falls onto the second guide rail 22 and the third guide rail 23, the upward stabilizing component 3 pushes the rectangular frame 41 so that the two first clamping frames 44 and the second guide rail 22 remain vertical, and the other two first clamping frames 44 and the fourth guide rail 24 remain vertical. In this reciprocating manner, the seedling trays can be placed in the greenhouse or seedling field in sequence, and the first guide rail 21 can be removed for recycling.

[0060] like Figures 8-10 As shown, the stabilizing assembly 3 includes magnet blocks 31 fixed on both sides of the rectangular frame 41. A guide rod 33 is movably mounted on the magnet block 31. A first metal stop block 32 is fixed on the top of the guide rod 33, and a second metal stop block 34 is fixed on the bottom of the guide rod 33.

[0061] When the swing plate mechanical body 1 slides to the other end of the rectangular frame 41 , it pushes the first metal limit block 32 , the guide rod 33 and the second metal limit block 34 downward, and the guide rod 33 and the second metal limit block 34 are engaged with the outside of the rectangular frame 41 .

[0062] The swing plate mechanical body 1 is supported by the sliding component 4, and the swing plate mechanical body 1 and the limit component 5 are pushed to slide along the slide groove 43 to the other end of the rectangular frame 41. At this time, the first metal limit block 32, the guide rod 33 and the second metal limit block 34 are pushed downward. The guide rod 33 and the second metal limit block 34 are located outside the rectangular frame 41, so that the swing plate mechanical body 1 and the limit component 5 are fixed to the other end of the rectangular frame 41 through the stabilizing component 3, preventing the swing plate mechanical body 1 and the limit component 5 from moving in the opposite direction along the slide groove 43.

[0063] The working principle and use process of the present invention:

[0064] The two main beams 25 are placed at both ends of the seedling raising field or the seedling raising greenhouse, and the first guide rail 21, the second guide rail 22, the third guide rail 23 and the fourth guide rail 24 are installed between the two main beams 25 through the docking block 27. The swing plate mechanical body 1 is placed on the first guide rail 21 and the second guide rail 22. The seedling raising plate is placed in the seedling raising field or the greenhouse in turn through the working movement of the swing plate mechanical body 1. The first guide rail 21 and the second guide rail 22 limit and guide the swing plate mechanical body 1 to make it move in a straight line, so as to avoid the swing plate mechanical body 1 deviating from the predetermined track during the movement due to the uneven ground of the seedling raising field or the greenhouse, causing the seedling raising plate to deviate;

[0065] The seedling raising plates are placed in the seedling raising field or greenhouse in sequence by moving the swing plate mechanical body 1 along the first guide rail 21 and the second guide rail 22. When the swing plate mechanical body 1 moves to the other end of the first guide rail 21 and the second guide rail 22, the cylinder 42 starts the output end to push the first clamping frame 44 and the second clamping block 46 downward, wherein the two first clamping frames 44 are clamped at the top of the first guide rail 21, the other two first clamping frames 44 are clamped at the top of the third guide rail 23, and the two second clamping blocks 46 are clamped at the top of the second guide rail 22. As the output end of the cylinder 42 continues to push out, the swing plate mechanical body 1 is propped up and the driving wheel is separated from When the first guide rail 21 and the second guide rail 22 come into contact, the swing plate mechanical body 1 and the docking plate 51 can be pushed to slide along the slide groove 43 to the other end of the rectangular frame 41. At this time, the driving wheel of the swing plate mechanical body 1 and the second guide rail 22 and the third guide rail 23 remain vertical. At this time, the first metal limit block 32, the guide rod 33 and the second metal limit block 34 are pushed downward. With the guide rod 33 and the second metal limit block 34 located outside the rectangular frame 41, the swing plate mechanical body 1 and the limit assembly 5 are fixed to the other end of the rectangular frame 41 through the stabilizing assembly 3, preventing the swing plate mechanical body 1 and the limit assembly 5 from moving in the opposite direction along the slide groove 43.

[0066] At this time, the output end of the cylinder 42 contracts in the opposite direction, and the driving wheel of the swing plate mechanical body 1 gradually falls onto the second guide rail 22 and the third guide rail 23, while the first clamping frame 44 and the second clamping block 46 gradually separate from the first guide rail 21, the second guide rail 22 and the third guide rail 23. Since the driving wheel of the swing plate mechanical body 1 falls onto the second guide rail 22 and the third guide rail 23, the upward stabilizing component 3 pushes the rectangular frame 41 so that the two first clamping frames 44 and the second guide rail 22 remain vertical, and the other two first clamping frames 44 and the fourth guide rail 24 remain vertical. In this reciprocating manner, the seedling trays can be placed in the greenhouse or seedling field in sequence, and the first guide rail 21 can be removed for recycling.
